This demonstration showcases the 3GPP Release 15 functionality of the Open5GCore. The demonstrator addresses the features enabling the interoperability with Non-Standalone and Standalone 5G RAN (N1-N2-N3-N11 interfaces), the data path diversity using PFCP and GTP protocols (N4-N9 interfaces) and the basic Service Based Architecture features. To be able to maintain compatibility with existing devices and technologies, Open5GCore maintains backwards compatibility with LTE-EPC. The demonstration will present the various features of the core network platform as well as its configurability.
